Hey boys seems like the vip group would be the best place to answer my questions.

I have a 2006 Lexus G300 AWD and have just purchased a set of megan Ex street coilers and a set of 20inch Vertini Magic wheels. The problem im having is that even with the damper **** turned all the way to the stiff side, I am still rubbing on the inner fender and the wheel still has to much travel. How can I stiffen up the ride so I can keep the car low.

Thx

 

is it rubbing when you turn or when your going over bumps? what size tires do you have on it?

 

It only rubs when I go over bumps...I rolled my fenders yesterday as well.

Front - 245/35/20
Rear - 275/30/20

How do some of your guy roll around with the rim flush to the outside of the fender and not crush the fender when you hit a bump?

 

What is the width of your wheels? I assume 9" front and 10" rear with those tire sizes.
If so, you need to take the front tires and put them on the rear wheels. Sell the rear tires (275's) and buy some 225/35/20's for the fronts. That will give you the stretch you need to clear the fenders.
The stretch won't be too crazy either so don't worry. Just for reference I have 225/40/19 on my 19x10 front wheels and 255/35 on my 19x11 rear wheels. 12k miles on them over some real crappy roads with no issues whatsoever. Oh ya, put about 42 psi in each tire.

 

with the coilovers............ if you compress the spring will it make the ride stiffer?

 

I have this problem myself sometimes (tucking tire). When i try to go up driveways or etc my tire hits my frame and i can't move anymore.

Its not the fenders hes hitting, its the frame itself. I guess the spring rates are too soft? But even at 18kg/12kg my fronts still compress like nothing

 

?????????????????????

 

if in fact your running a 245 on a 9. wow thats a wide trie on a small width. im running 225 on 8.5 with no to hardley any strech. so your 9 should b fine with a 225

 

hammer the inside wheel tub where your tire hits. I wouldnt rub the actual rolled area of the fender but the inner tub itself. Hammer that part flat and you'll be good to go

 

your rubbing because your tires are too big. you should have went with a 245/30

as far as dampening, no. compressing the spring (or upping the pre-load) is only going to allow the spring to travel less and possibly wear the coilovers out quicker because there is no room for travel.
